Serial No. 489,440, June 3, 1943, which is a division of Serial No.437,719, April 4, 1942. Application for reissue July 24, 1946, SerialNo.

11 Claims.

The present invention relates primarily to facsimile telegraph systemsand apparatus and particularly to mechanisms and the control thereof forsupplying such facsimile apparatus with and the removal therefrom ofmessage sheets and recording blanks.

*This application is a division of application Serial No. 437,719, filedApril 4, 1942, System and apparatus for facsimile telegraphy.

While the principles of the present invention are particularly adaptablefor use in conjunction with a combined facsimile transmitter-recorder ofthe rotating-cylinder type, such as for example that disclosed in PatentNo. 2,255,868, granted November 11, 1941, to R. J. Wise et al., and isdescribed in a facsimile system employing such a machine and otherrotating cylinder type facsimile machines, it will be evident that theprinciples of the invention are not limited in application to only thesefacsimile machines and the system described, but may be applied tovarious other types of machines and systems.

The transmitter-recorder facsimile machine disclosed in theabove-mentioned Patent No. 2,255,868 includes a rotatable drum, and whenthe machine is used in a receiving capacity a recording blank is Wrappedaround the drum so that the subject matter received is reproduced on therecording blank by the usual means of a stylus which explores successiveareas on the recording blank and marks the same in accordance withsignals received. When the machine is employed as a transmitter, themessage sheet is wrapped around the cylinder and successive areas of thesheet explored by a photoelectric pickup system and correspondingsignals transmitted to a line circuit.

In accordance with the above, one of the primary objects of thisinvention is to provide selectively controlled means whereby .therotatable cylinder or cylinders of a facsimile machine for example maybe supplied with either a message blank or sheet in the conditioning ofthe machine for the transmission of a message or with a recording blankin order to condition the machine for the recording of a message.

Another object of the invention is to provide for the selectivedistribution of message sheets and/or recording blanks removed from therotating cylinder of a cylinder type of facsimile transmitting machine,receiving machine, or combined transmitting and receiving machine.

These and other objects of the invention will be apparent to thoseskilled in the art as the following description of the apparatusproceeds together with the description of a facsimile system employingsuch apparatus with reference to the accompanying drawings, in which:

Fig. 1 is an elevational view partly in section of a combinedtransmitter-recorder constructed in accordance with the invention;

Fig. 2 is a fragmentary detail view in perspec- 5 tive of the copyholdercylinder of the machine of Fig. 1;

Fig. 3 is a wiring diagram showing a circuit arrangement for controllingand operating the combined machine of the present invention;

Fig. 4 is a wiring diagram showing the central ofiice equipment forcontrolling and operating a number of machines embodying features ofthis invention;

Fig. 5 is a fragmentary View similar to Fig. 1 of a modified machine;and

Fig. 6 shows a modification of Figs, 3- and 4.

In the present invention the novel facsimile transmitter-recorderdisclosed herein is connected by a. communication circuit to acommunication center equipped with a transmitter, a message recorder,and a. monitor recorder. These three. pieces of central oflice equipmentare arranged to be connected to any incoming communication circuithaving one or more of the automatic facsimile transmitter-recorders ofthis invention connected thereto. The central ofiice transmitter andmessage recorder may be combined into one automatic machine which is ofthe drum changing type similar to that described in the said Patent No.2,255,868, and the monitor recorder may be of the type disclosed in Fig.41 of the drawings of Patent No. 2,255,869,. granted to- G. H. Ridingset al. September 16, 1941. To simplify operation of the system, themonitor recorder may be mechanically driven from the central officetransmitter whether or not the latter is combined with the centraloffice message recorder.

The combined transmitter-recorder disclosed in Figs. 1 and 2' mayinclude structural refinements shown and claimed in Patent No.2,262,715, granted to R. J. Wise et al. on November 11, 19.41, forSystem and apparatus for automatic facsimile telegraphy, and also in theapplication of R. J. Wise et al., Serial No. 389,164, filed April 18,1941, for System and apparatus for facsimile telegraphy.

The combined transmitter recorder 15 is housed in a box 11' which may beplaced in any location accessible to a person authorized to collect anddistribute received messages or to a member of the general public havinga message for transmission. The box H is provided with a bin l2 forreceiving message sheets ejected from a co-pyholding cylinder It uponoperation of a stripping fhager IS. The bin 12 is accessible through anopening I"! in front of the box, which may be provided with a lockedclosure 18 if desired. The key for this closure may also operate a lockA series of five signs 2| provided with illuminating lamps 22a to 22sare located in the front panel 23 of the box I I. The lamps arecontrolled from the central oflice to illuminate the signs atappropriate times whenthemachine is used as a. transmitter in a mannerto be described.

The message sheet receiving slot 24. is provided for the insertion ofmessage sheets bearing subject matter to be transmitted when the machineis to be used as a transmitter. The slot 24 communicates with a chute26, which may be formed as shown between the inwardly directed upperpart 21 of the panel 23 and the horizontal portion of an angularly bentcover plate 28' which protects the paper feeding mechanism.

These externally accessible portions of the equipment are all that needbe manipulated and observed in operating the machine as a transmitter.The recording functions of the machine are controlled solely from thecentral ofiice and access thereto is not needed except for purposes ofadjustment, when required.

The upper portion of the box II houses the feeding mechanism forsuccessively delivering individual recording blanks to the copyholdingcylinder I4. As illustrated, the paper feed includes a roll 3| ofindividual blanks 32 supported, preferably in overlapping relationship,as shown in the copending application, Serial No. 389,164, abovereferred to, on an elongated belt 33 of any suitable material, the endof the belt being secured to a mandrel 34. The belts and the blankssupported thereby are rolled together around the mandrel to form theblank supply roll 3|- The opposite ends of the mandrel may beconveniently supported in notches 36 in a pair of reel supportingbracket arms 31 mounted on the upper front panel 38 of the box II. Thebelt 33 passes downwardly around the lower edge of the panel 38 andthence to "a belt takeup reel 39 which is in driving engagement with amotor (not shown) contained within the housing 4!.-

Unwinding of the belt 33 and the blanks 32 releases them one ata time,permitting each blank to drop onto the copyholding cylinder I4,provideo. with teeth 42 as disclosed and claimed in Patent No.2,262,715, referred to above. A hinged cover 44 gives direct access tothe reel 3|, and a side panel or cover plate 46 may be removed.

to facilitate removal of the belt 33 after it has been wound on themandrel 33. It will be understood that the structural elements andindicating devices disclosed in the application. Serial No. 389,164above referred to may be associated with the paper supply reel 3 I.

The copyholding cylinder I4 is mounted on a shaft 41 supported insuitable bearings and driven from a motor 48, indicated diagrammaticallyin Fig. 3 of the drawings, which also drives a lead screw 49 in awell-known manner.

A peripheral groove 5| formed in the cylinder and receives a finger 52secured to a rock shaft 53 rotatably mounted at each end in any suitablemanner in the frame of the machine In. The rod into the position shown,aifording a convenient means for controlling the locking magnet 53 ofthe chute 26 and the tape reel motor'which is operatively connected tothe mandrel 33.

A presser roller 5| is rotatably mounted on a stem 62 projectingoutwardly from a bracket arm 63 pivoted at 54 to a stationary portion 56of the machine frame. A spring 61 resiliently urges the roller 6I intoengagement with the periphery of the cylinder I4. The roller 6| isgrooved at 69 to accommodate the teeth 42. The roller BI in conjunctionwith the teeth 42 serves to draw either a recording blank 32 or amessage sheet bearing subject matter for transmission onto thecopyholding cylinder I4.

A scanner carriage is, housing and supporting the optical transmitterscanning device II including a chopper motor 12 (Fig. 3), the recordingstylus I3 and the stylus operating magnet I4, is supported for scanningmovement longitudinally of the cylinder I4 on a rod I6 by a beveledroller I'I' mounted in brackets 78 on the bottom of the. box. Aninverted U-shaped bracket IS in the upper portion of the box slidablyembraces a guide rod 8 I. The stylus 73 is carried on a pivoted arm 83,the projecting end 84 of which is the armature of the stylus magnet 14.

A half-nut 86 is located beneath the scanning box for vertical movementinto and out of en-' gagement with the feed screw 49. This range ofvertical movement is provided by securing the half-nut 86 to a pivotedarm 88, one end of which serves as an armature for the half-nut magnet.

39. A spring 9! serves to maintain the half-nutout of engagement withthe lead screw until themagnet 89 is energized. A pair of contacts 92are brought into circuit-closing engagement when the half-nut magnet 89is energized. Scanningmovement of the carriage 10 also occurs when thehalf-nut magnet 89 is energized.

The circumference of the recording cylinder I4 is preferably such that,when a blank 32 is wrapped around the cylinder for scanning, its edgesoverlap slightly to provide a smoother path for the recording stylus andto prevent its. contacting the drum. In order to facilitate stripping:the blank from the drum after scanning, each blank is preferably notchedin one corner, as at.

90, in Fig. 2, in such a way that, when the blank is on the cylinder,the notch provides anopen space between the edges at one end. This spacepermitsthe stripping finger Iii to be inserted through the open spaceand under a blank for the purpose of stripping it from the cylinder. Ifdesired, the message sheets to be inscribed with subject matter fortransmission may be shorter than the circumference of the cylinder I4,providing a space between their edges when inposition to facilitateoperation of the stripper finger I6. The portion of the light reflectivedrum which is exposed between the edges of the sheet} in either case maybe used in conjunction with the optical scanner II to derive a framingsignal. Also, a contact arm may bear on thecylinder and makecontact withthe exposed cylinder for the purpose of providing a framing signal. Thestripper finger I3 is adjustably secured to a rock shaft33 by a setscrew 94. The rock shaft 93, journaled in any suitable manner inthe;frame of the machine Iii, carriesthe armature 96 of a strippermagnet91. A return spring 98 maintains the stripper finger out of'engagementwiththe cylinder I4 until :the magnet 91 isenergized;

In operation of the mechanical features thus far described and assumingthat the machine is to be used as a recorder, the ,motor'associatedwiththe blank feeding mandrel 39 is energized over a circuit to be describedin connection with Fig. 3 of the drawings, or over any desired circuitwhich includes the contact 56 and the switch arm 54. A blank 32 will bereleased and wrapped around the cylinder I4, whereupon the circuitcontrolling the motor will be interrupted. During the scanningoperation, the feed screw 49 is rotated from the motor through the feedscrew driving gears to produce the necessary scanning movement of thescanning carriage I and the stylus I3 longitudinally of the rotatingcylinder. When scanning is completed, or at any desired time, the half-nut 86 is disengaged from the carriage feed screw, permitting thecarriage to be returned to its. starting position by a strand or cordunder tension secured to the carriage, as shown in Patent No. 2,262,715.Upon completion of a scanning operation, the magnet 91 may be energized,causing the stripper finger to strip the message sheet from the cylinderso that it drops into the bin I2.

When the machine is to be operated as a trans" mitter, the lock switchor push-button I9 is operated, following which the chute lock magnet '59is energized in any desired manner, either locally at the machine Ill orfrom a remote point with which communication is desired. The armature ofthe magnet 59 is connected by a link IGI to a bell crank I02 whichcarries a bar 13 normally obstructing entrance to the chute 25.Insertion of the message sheet in the proper manner may be insured bybeveling one corner of the blank for cooperation with an arrangementsuch as is disclosed in Patent No. 2,262,715, referred to above.

When the sheet in position on the cylinder I4 bears subject matter fortransmission, the optical scanning device I2 will be in operation withthe stylus I3 retracted.

The transmitting and recording equipment I04 installed at a centraloihce for interconnection with one or more of the machines III is showndiagrammatically in Fig. 4 of the drawings. A suit-- able machine of theautomatic drum changing type combining transmitting and recordingfunctions is shown in complete detail in Patent No. 2,255,868, referredto above. Separate amplifiers IE6 and I! are provided for thetransmitting and recording functions, respectively, of the machine I04.A signal inverter I08 feeds the recording stylus I09. The monitorrecorder III, as stated above, is disclosed in Fig. 4 of Patent No.2255,869. An amplifier II2 feeds the recording styli II4 of the monitorrecorder. It will be understood that any type of facsimile equipment maybe employed at the central ofiice. However, the arrangement of apparatusto be described is quite convenient and represents a desirableembodiment of the system of this invention. The combinedtransmitter-recorder, I04 is driven through a gear mechanism M by amotor III; which operates in synchronism with the motor 48 of themachine or machines I0 and drives a power shaft I I! through aconstantly engaged friction clutch H8. The shaft II'I drives thetransmitter-recorder I04 through any suitable means, such as the gearand pinion combination H9 and I2I, diagrammatically shown. The stylusmoving mechanism I22 and the paper feed mechanism I23 of the monitorrecorder are also driven from the shaft 1, for example, by a worm andworm wheel combination I24 and I26, also represented diagrammatically inFig. 4 of the drawings. The shaft H1 is. locked against rotation by atooth or pawl I21 onan armature I28 pivoted at I29 which engages a notchI3I' formed in a disc I3 2 which is secured to the shaft. A spring I33serves to withdraw the tooth I21 from the notch I3I upon deenergizationof. a phasing or framing magnet I34. The gear ratios of the worm andworm wheel combination I24 and I26 are selected so that a copy-holdingdrum I35 of the transmitter-recorder I04 rotates once while a recordingstylus II4'of the. monitor recorder traverses its recording strip I36.This arrangement is employed, as it simplifies phasing or framing ofsubject matter transmitted from one of the machines III. The blanks uponwhich incoming messages are to be recorded and the message sheetsbearing subject matter for transmission to the machine III are mountedon the copyholding drums I35 which are inserted in thetransmitter-recorder appaa ratus I94 one at a time, as shown andexplained 'in Patent No. 2,255,863. The recording drum in operativeposition is rotated by power supplied from the shaft I I! and duringrotation the marking stylus I05 or a light spot from an opticaltransmitting scanner I31 scans the message sheet in a direction parallelto the axis of the copyho1d ing drum. Mechanism similar to thatdisclosed in the patent is provided for removing a copyholder drum withits attached message sheet after a scanning operation.

The transmitting and recording amplifiers I06 and It? and the monitoramplifier II2 are connected to the contact studs of the fifth and sixthlevels of a rotary switch I38 made up of eight levels. Each level isprovided with twenty-one contact studs and a movable contact arm. Theeight contact arms are designated I39a to I39h and are movedsimultaneously, Each is provided with abridging wiper MI wherebyconnection is made with each of the studs before the connection with thepreceding stud is broken. The contact arms I39a to I39h of the switchI38 normally remain in the neutral position (Fig. 4) when the system isidle; and are moved in a counterclockwise direction, as shown in Fig. 4,from the neutral position over thirteen studs when a message is to betransmitted to a machine Ill, and in the opposite direction from theneutral position over eight studs when the central station attendant isresponding to acall from one of the machines II! and is taking the stepsnecessary to record an incoming message.

The communication circuit connecting a single machine or a plurality ofmachines I 0 and the central ohlce is shown as a line L comprising apair of conductors LI and L2, which are used simultaneously for thetransmission of the alternating current facsimile signals or messagimpulses andthe direct current control signals by which selection andoperation of a machine III is obtained.

When a machine I is in use as a transmitter, the facsimile signalsoriginate at the optical scanning device 'II including a light source'II' which is connected to an amplifier I42, as shown in Fig. 3, theoutput circuit of which is connected to a pair of contacts I43 of arelay I44. When the machine I is in use as a recorder, the incomingfacsimile signals are applied to a receiving amplifier I46 and to thestylus I3 by way of make contacts I41 of the relay I44. The tongues ofthe relay which cooperate with the contacts I43 and I41. are connectedthrough a pair of blocking condensers I48 to the line conductors LI andL2. The purpose of the blocking condensers is to isolate the alternatingcurrent facsimile signals from the direct current control signals. The:

polarity of the direct current potentials which are applied to theconductor LI is controlled by the apparatus at the central office forthe purpose of operating a polar relay I49 connected to this conductorat the machine I0. Similarly, the

- polarity of the direct current potential applied to the conductor L2is controlled by the apparatus at the central ofiice for the purpose ofoperating a polar relay I5I connected to this conductor at the 'machineI0. Each of these polar relays is of the three-position type, wherebythe tongue is moved to one extreme contact in response to the polarityof potential, to the other extreme contact in response to the oppositepolarity of potential, and to a mid position disengaged from both of theextreme contacts in response to a no-current condition. The tongue I52of the relay I49 cooperates with contacts M and S. The tongue I53 of therelay I5I cooperates with the contacts M and S.

It should be understood that a number of machines IIJ, as stated above,will normally be connected to a single communication circuit in a partyline system, and that each machine I9 is adapted to be locked'againstoperation when any other machine on the same line is operating, as willbe described hereinafter, and as is fully set forth in Patent No.2,262,715.

1 The operation of the complete system will be described in connectionwith Figs. 3 and 4 taken together. It is assumed that power is suppliedat the machine I 9 by connecting a suitable source of alternatingcurrent I55 through a switch I56 to the bus bars A and B. The switch I56is kept closed to maintain the heaters of the amplifiers I42 and I46 fedfrom the transformer I51 in condition for immediate operation. Themotors 48 and 12, the plate supply for the amplifiers and the lightsource or other active element of the optical scanner are controlledfrom the central ofiice following operation of the push button I9 orselection of themachine by the central office.

Operation of the system to select and communicate with a particularmachine III will first be described. The attendant at the central officeinserts the copyholding drum bearing the message to be transmitted inposition in the transmitterrecorder I 94 by operating a key I6I (Fig. 4)This corresponds to the key 221 disclosed in Fig. 3 of Patent No.2,255,868 and operates the drum changing relay I62. The drum changingrelay I62 is also controlled by the contact'arm I39h of the rotaryswitch I38. A plug I63 is inserted in the line jack I64 of the line L towhich the desired machine I0 is connected. This connects the lineconductors LI and L2 through a pair of blocking condensers I66 andthrough a power level adjustment pad I61 to the movable arms I39d andI390 of the rotary switch and disconnects the line amplifier I66 and itsassociated equipment, which is not needed at this time, from the line L.The line conductors LI and L2 ar also connected through a pair ofinductances or choke coils I69 to the control signaling apparatuscomprising the contact arms I39b and I39a of the rotary switch.

The contact arm I391), in its neutral position, rests on a contact studto which the positive pole of a suitable source of direct currentsignaling potential is connected. Referring to Fig. 3, it will be notedthat line LI controls operation of the three-position relay I49 and,when a positive potential is applied to this relay, its tongue I52cooperates with th contact M to complete a circuit through the steppingmagnet coils I1I not be operated because of the of a' selector switchI12. The connection to line LI at the central ofilce includes a dialingdevice,

terrupter consisting of a cam engaging the impulse springs. The linecircuit is normally closed, and the impulse so-called is a briefinterruption of the line current. These impulses or cur-. rentinterruptions are effective to step the switch arm I14 of th selectorone point for each impulse. With the selector diagrammatically shown byway of example in Fig. 3, insertion of the plug I63 into the jack I64 atthe central office will cause the switch arm I14 to move to its secondcontact stud. To select the machine III of Fig. 3, the dial will bemanipulated by dialing N0. 4, which will produce four successiveinterruptions, stepping the switch arm to the fifth contact stud towhich the operating coil of a relay I16 is connected. Th system ispreferably so designed that when positive potential is removed from theline LI, it is applied to line L2- to maintain the selection of themachine by way of the make contact 92 of the switch associated with thehalf-nut magnet and energization of its relay I16. Stepping of theselectors of other machines connected to the line L occurs, butnoselection will result, as their relays I16 will presence of contactsI11.

The effect of the positive potential maintained on the line conductor LIor on the line conductor L2 is to maintain the busy signal lamp 22ailluminated in all the machines connected to the line L. The circuit ofthe signal lamp 22a.

with positive potential applied to LI may be traced from the bus bar Bthrough the contact tongue I52 and contact M of relay I49, the

break contacts I18 of a multicontact switch I19 to bus bar A. Thecircuit for the signal lamp 22a with positive potential applied to L2may be; traced from th bus bar B through the make contact 92 of theswitch associated with the: half-nut magnet 89, the break contactsI18'0f the multicontact switch I 19 and the lamp 22a to the bus bar A.The push button I9 at the selected machine III and at the other machinesconnected to the line L is rendered ineffective by' a break contact I8Iof a relay I82 which is connected in parallel with the signal lamps 220.When the calling plug at the central ofiice is inserted in the linejack, placing a plus-potential on line LI,

terminal being connected to the bus bar B whereby this magnet becomesenergized to attract its armature I84. As the facsimile communicationprocess is carried out in a manner to be de-' of this armature movesbeneath the armature I I16 of the multicontact switch I19 to,lock it inthe upper or 011 position shown. This occurs at the other machine on theline L as well as. the selected machine I 9.

The selector arm I14 is shown as being stepped,

by a. pawl I88 which engages the teeth of'a ratchet wheel I89 carried bya shaft I9I towhich 22a and bus bar A is connected to one ter? minal ofthe magnet I83 through the tongue I52 and contact M of the polar relayI49, the otherbus bar B throughthe make contact 92 of the switchassociated with 9 the switch arm I14 is secured. A pawl I92 also engagesthe teeth of the ratchet wheel and maintains the selected position ofthe arm I14 while the stepping magnet coil i1I is deenergized. A coilI90 is provided for withdrawing the pawl I92 from the teeth of theratchet when it is energized in a manner described below. One side ofthis coil I90 is connected to the alternating current bus bar A, thecircuit being completed under conditions described below to the bus :barB through a thermal time delay switch I94. The coil I99 of the thermalswitch H4 is energized through a pair of cooperating contacts I95, themovable one of which is carried by the pivoted armature I96 of thestepping magnet I TI. With this arrangement, the magnet coil I90 isnormally deenergized, even during the selecting operation, as the timeof closure of the contacts I95 during a stepping pulse is insufficientto cause heating of the thermostatic bar !81 of the thermal time delayswitch I 94. When the selection is completed, energization of thestepping magnet IN is maintained, which maintains the circuit throughthe heater element I99 by way of the contacts I85, for a sufflcientperiod to effect closure of the contacts of the thermal switch, thusenergizing magnet Hit. The pawl I92 is thus retracted so that theratchet wheel I89 is free to return to its normal position under theinfluence of the torsion spring 250 when the central office attendanthas completed the steps to be described of transmitting a message to themachine Ill and checking its receipt.

The relay I16, which is energized upon selecing the machine Ill by thedial H3, completes a circuit through its make contact 21H, which circultincludes the coil of the send-receive relay I44 and the contact S of thepolar relay I49. This circuit enables the central oilice attendant tocontrol the transmitter and recorder functions of the machine I8 byreversing the polarity applied to the line LI. When the negative pole ofthe signaling current source is connected to the line LI, relay tongueI52 moves to the contact S, thereby energizing the relay M4 to connectthe receiving amplifier I 46 to the lines LI and L2. The make contact204 of relay I16 serves to control the connection of the amplifiers I42and I45 across the alternating current bus bars A and B and, also,energizes a relay 285 over the conductor 206 which closes the circuitfrom the amplifiers to the line L at its make contact 221i. This relayis included for connecting the amplifiers to the line only when power isapplied to the machine so that, in party line operation, only themachine in use will be bridged across the line, and the signal will notbe weakened by the unnecessary connection of other machines on the line.The cylinder driving motor 48 and the light chopper motor 12 of theoptical scanner 1! are also energized over the conductor 286 when therelay I 15 is energized by selection of the machine.

The rotary switch I38 (Fig. 4) is moved from the neutral positioncounterclockwise to the first position to obtain a positive check of theselection of the desired machine I0. Positive potential is maintained onLI by the contact arm I391), and positive potential is connected to L2by the arm I390. whereby the half-nut magnet 89 of the selected machineis energized to scan a distinctive mark 209 (Fig. 2) which is repeatedaround the periphery of the .copyholding cylinder I4. In the exampleshown, the mark 209 takes the form of letters SK, and it will beunderstood that the copyholding cylinders I4 of the other machinesavailable for selection will also be provided with distinctive marksdiilering from each other. The contact arms I38c and I38d of the rotaryswitch I38 in its first position connect the lines LI and L2 to theamplifier II2 of the monitor recorder III by Way of the blockingcondensers I66. The marks 209, in this instance SX, will be recorded onthe web or strip I36 of recording paper in the monitor recorder. Thepaper feed mechanism of the monitor recorder operates, since the relay2I0 is deenergized at the contact arm I39), and the latch I29 iswithdrawn from the notch l3l, since the arm I395! opens the circuit ofthe looking coil 2 I 4 of the relay 2| 6. It will be noted that,inasmuch as the marks are repeated upon the periphery of the copyholdingcylinder I4, phasing of the machine I8 with the monitor recorder III isnot necessary at this time, as one or more of the marks will bereproduced in their entirety. The rotary switch I38 is maintained in itsfirst position until the central office is satisfied that the desiredmachine III has been selected.

The rotary switch I38 is next moved to its second position to secure amessage blank 32 on the copyholding cylinder of the selected machine.This is accomplished by placing a negative potential on conductor LI andmaintaining the connection of the conductor L2 to the positive pole ofthe signal source. At the machine I0 this energizes the relay I44,incidentally connecting the selected party's receiving amplifier I46 tothe line, but it has no function at this time. The half-nut magnet 89remains energized, causing the stylus to feed, but this action is alsoincidental. Energization of the relay I44 in the man ner just explainedcompletes a circuit from the bus bar A by way of the switch arm 54 andthe cooperating contact 56, a make contact 2 of the relay I44 and a makecontact 2I2 of the relay I16 to the driving motor of the message feedingdevice 4|. The message blank 32 is thereby applied to the copyholdingcylinder I4 in accordance with the description above, which raises thefinger 52 from its groove and breaks the circuit which was made at thecontact arm 54 and contact 56, stopping'the driving motor of the sheetfeeding device 4 I.

The next active step, which is the fifth position of the rotary switch,phases the selected machine It] with the combined monitor andtransmitterrecorder at the central ofiice, and to do this it isnecessary to apply positive potential to the conductors LI and L2.However, to insure the main tenance of communication with the selectedmachine IO, two transition steps of the rotary switch I38 are included.The third position reverses the polarity of conductor LI and holdsconductor L2 positive to avoid losing the selected party. The fourthposition opens the connection to the conductor L2 with the signalingsource, thereby spacing back the scanning carriage 10 of the selectedpartys machine I8. If,-in the fifth or phasing position mentioned above,a black line on the blank 32 is used extending all the way across theblank instead of a black spot of limited area in a definite position,the back spacing step provided by the fourth position will not benecessary, as the phasing signal will be generated at all points in thelongitudinal travel of the carriage 10.

When the rotary switch 138 is passing over its fourth position to itsfifth or phasing position noted above, a coil 2 of a relay 2I6 isenergized at this time by way of contact arm I399 and thereby energizesa relay 2l1 by applying ground at a make contact 2I8. In the fifthposition of 1 1 the rotary switch, the circuit of the coil 2I4 isopened; however, the relay 2 I4 stays up, since its coil 226 isenergized from ground at make contact 2I3, switch arm I33e and the makecontact 221 of the phasing relay 224. The relay 2" energizes the phasingmagnet I34 at its make contact 2I9 and also energizes the half-nutmagnet 220 of the transmitter-recorder section I04 of the central ofliceequipment, This steps the transmitterrecorder I04 and also the monitorrecorder II I until the scanning light spot at the machine I passesover'the non-reflecting mark 222 (Fig. 2) on the recording blank inposition on the recording cylinder I4 at the machine I0. This causes adrop in the signal fed to the phasing amplifier 223, resulting insubstantial deenergization of the relay 224, which opens the circuit ofthe locking coil 225 of the relay 2I6 at the make contact 221.Deenergization of the locking coil 226 of the relay 2I6 opens thecircuit of the relay 2II, resulting in release of the relay 2I'I,starting the shaft ill to drive the monitor recorder III in phase withthe machine I0. Operation of the carriage of the machine I04 isincidental. If the exposed portion of the reflective cylinder is usedfor the purpose of deriving a framing signal at the machine I0, thephasing relay may be of the high current type provided with a breakcontact instead of a make contact. The signallevel will be higher whenscanning the bright drum than when scanning the less reflective surfaceof the message blank.

As the amplifier II2 of the monitor recorder III is connected to theline L at this time by the contact arms I330 and I 39d of the rotaryswitch I38, a portion of the blank will be scanned, thereby checkingpositively application of the blank to the copyholding cylinder of theselected machine I0 by a record on the web 2 I 0.

The sixth and seventh positions of the rotary switch I38 are carriagespace back and transition steps, respectively. In the sixth position thepositive pole of the signaling source is connected to line LI by way ofthe contact arm I391), and the line L2 is unconnected at this time. Inthe seventh position positive potential is maintained on the line LI,and the line L2 is also connected to the positive pole of the source ofsignaling potential by way of the contact arm I39a.

Transmission from the central office to the se- 1 lected machine occursat the eighth position of the rotary switch I38. The contact arm I39bconnects LI to the negative pole of the source of signaling potential,and the contact arm I39a connects the line L2 to the positive pole ofthe signaling source. The negative potential on line LI moves thecontact tongue I52 of the relay I43 to its contact S, operating thesend-receive relay I44. The positive potential on the line L2 which ismaintained from the previous step causes the p carriage 10 of theselected machine I0 to feed. The stylus magnet I4 is energized at thistime from the bus bar A through the arm 54 and contact 51 of the papercontrol switch, the operating coil of the stylus magnet, a make contact232 of the relay I44 to the bus bar B. The rotary switch is left in itseighth position until the message on the copyholding drum at thetransmitter I04 has been completely scanned, after which the rotaryswitch is moved through its ninth and mits the carriage I0 of theselected machine to return to its initial position.

The eleventh position of the rotary switch'is' effective to permit thecentral station attendant to obtain a record of all of any portion ofthe subject matter which was recorded on the message blank at theselected machine in the eighth position of the rotary switch. Positivepotential is connected to the lines LI and L2 which, in ac-' cordancewith the previous description, deenergizes the'send-receive relay I44 toconnect the sending amplifier I42 to the line and also to causeengagement of the half-nut with the lead screw 49 to propel the carriage10. The rotary switch is maintained in this No.11 position until therecord appearing on the monitor recorder satisfies the attendant thatthe message has been received.

The twelfth position of the rotary switch maintains Ll positiveandconnects line L2 to the negative pole of the source of signalingpotential; which moves the contact arm I53 of the three position'relayI5I against its S contact to energize the peel magnet to remove theblank 32 from the drum. The switch arm 54 of the selected.

machine I 0 comes in contact again with the contact 53, therebypreparing the circuit which places a new blank in position upon the nextoperation of the relay I44, in accordance with the previous description.This contact also connects the magnet 59 of the chute locking mechanismacross the bus bars A and B. However, this circuit is interrupted atthis time at the'make contact 233 of a-relay 234, the operating coil ofwhich is connected from the bus bar 13 to the bus bar A in parallel withthe deposit message signal lamp 22b over the conductor 236. Theconductor 231 for feeding the lamp 22b is connected to the make contacts238 of the multicontact switch H! which are closed only when thepushbutton I0 is operated by a person desiring to operate the machine I0 asa transmitter. The relay 234, therefore, permits the chute 24 to openonly when the machine I0 or the machine I0a is operative as atransmitter and the copyholding cylinder I4 does not contain a messagesheet. Also, in the twelfth position of the rotary switch I33 itscontact arm I339 energizes the coil 2I4 of the relay I26, thereby tostop the copyholding drum of the transmitter-recorder I04 and energizeits half-nut to efiect a'carriage return. The contact arm I39h energizesthe relay I62 to eject the copyholding drum from the machine I04 in themanner described in Patent No. 2,262,! 15 referred to.

The thirteenth'position of the rotary switch is similar to the firstposition. The monitor re corder amplifier H2 is connected to the com:munication circuit L, and the selected machine I0 is operated as atransmitter byplacing a positive potential on the lines LI and L2. Transmission from the machine I0 need be continued only until a record. isobtained oi the distinctive mark 209 on the copyholding cylinder.

The central station attendant may now remove the plug I63 from the jackI54 which turns off the selected machine I0 by deenergizingthe steppingmagnet coil III, permitting the pawl I88to release the ratchet wheel,I89. The mag net I30 is energized atthis-time through the thermal timedelay switch I94,.tl 1ereby' keeping the pawl I02 from engagement withthe teeth of the ratchet wheel at this time.- After a short.

time interval, the thermostatic bar I of the switch I94 cools and opensthe circuit of the magnet I30 which permits the pawl I92 to drop sacs-rin place in readiness for the next operation of the selector.

-'When the contact arm I74 of the selector is returned to its normalposition, the relay I16 is deenergized, which disconnects the powersupply from the amplifiers at the make contact 204 of the relay, therebystopping the motors and disconnecting the amplifiers. The relay 205 isdeenergized, which disconnects the sending amplitier I42 from the linesLi and L2 for the reasons stated above.

The rotary switch I38 at the central oflice is preferably returned toits neutral position when the operator removes the plug I63. However, ifthe switch is left in the thirteenth position inadvertently, selectionis possible, since the posi tive pole of the signa ling source isconnected to LI when the plug is next inserted to select a machine Ill.

If the central o-fiice attendant is dissatisfied with the appearance ofthe record obtained on the strip I36 of the monitor recorder when therotary switch was in its eleventh position, he may move the rotaryswitch to position twelve to remove the unsatisfactory copy and returnit to the second position to place a fresh blank on the machine and thenre-run the transmitter at the central ofiice. Before doing this, he may,if he so desires, write the words second transmission or words ofsimilar import on the original message mounted on the copyholding drumof the transmitter so as to apprise the person removing the receivedmessage from the bin I2 at the machine III that two of the record sheetsto be found there are duplicates. This will avoid any confusion whichmay result if the first transmission is so poor that it cannot bedeciphered and will be a clear indication that the transmission has beenrepeated.

The steps of the entire process of selecting and transmitting a messageto the machine II) will be accurately "recorded on the web I33 of themonitor recorder III and may be preserved at the central oflice foraccounting and other purposes.

Any one of the machines I may be operated as transmitters in a mannersimilar to that set forth in detail in Patent No. 2,262,715, referred toabove. The rotary switch I38 is, therefore, provided with eight stepswhich are covered by the contact arms I39a :to I39h when these contactarms are moved in a clockwise direction from the neutral position.

To use any one of the machines It! as a transmitter, the patron or otherauthorized person operates the push button l9 or its equivalent, therebyenergizing the operating magnet 24I of the multiconta'ct switch I19.This results in closure of the make contacts 242 which perform the samefunction as the make contact 204 of the relay I16. The amplifiers of themachine are energized at this time, and the driving and light choppermotors 48 and I2 are started. An alternating current signal is generatedby the optical pickup dei ice II which is received by the previouslymentioned line amplifier IE8 at the central oili'ce. The output of thisamplifier energizes a relay 243 which in turn energizes a, relay 244 byway of .a make contact 246. A make contact 241' of the relay 244 lightsa, supervisory lamp 248 to apprise the central station attendant thatacall is to be answered and also connects the positive pole of asignaling source, which may be the signaling source previouslymentioned, to line LI.

'14 The positive potential on the line LI moves the contact tongue I52of the relay I 49 to'its contact M, thereby illuminating the depositmessage lamp 22b over the closed contacts 238 and also looking theswitch I19 by energizing the locking magnet I 83.

The patron will now insert in the slot 24 a message sheet inscribed withthe subject matter to be transmitted, the slot being open at this timeby reason of the energization of the relay 234 over the conductor 236.When the message sheet is wrapped on the copyholding cylinder I4, theswitch arm 54 interrupts the circuit of the chute locking magnet 59which was maintained at the contact 56.

The central station attendant, responding to the signal lamp 248,inserts the plug I 63 in the jack I64, which disconnects the lineamplifier I68 but maintains LI positive over the contact arm I391). The.receiving amplifier Ill'I at the central office is maintained incommunication with the line L over the contact arm I390 and I39d of therotary switch I38. The attendant may now move the rotary switch I38clockwise from the neutral position to its first position, which is, asregards the polarity of LI, the same as the neutral position. L2 ismaintained open. The coil 2I4 of the relay H6 is energized by way of thecontact arm I39g to prepare the phasing circuits originating at the makecontact 2 I8.

If a. copyholding drum bearing a record blank is not in position in thecentral oflice recorder, the key 5| may be operated to insert acopyholder in the machine. However, one will usually be present if themachine has been previously used as a recorder, and the message drumfeeding magazine of the machine is provided with copyholding drumshaving message blanks.

The attendant will now move the rotary switch I38 to its second positionif he has not immediately done so after inserting the plug I63. In thesecond position of the rotary switch, line L2 is connected to thepositive pole of the signal source, line LI being maintained positive.The contact tongue I53 of the relay I5l moves to its M contact, engagingthe half-nut 86 to start the scanning process at the machine Ill. Thelamp 22c 01 the message being transmitted sign is illuminated. Also, inthis position of the rotary switch, the holding coil 2I4 of the doublecurrent relay ZIE is deenergized so that this relay may respond to thedrop in carrier current energy which occurs when the spot of light fromthe light source in the optical transmitter II passes over the blackspot on the message sheet in position on the cylinder I4. The stylus IDSis brought in contact with the record blank by a stylus magnet 249 whichis energized at this time by way of the arm I38) of the rotary switch.

Recording is permitted to proceed until the central station attendantobserves that the entire subject matter has been recorded by the machineIM, whereupon he moves the rotary switch I38 to its third position,which energizes the relay I62 to remove the copyholder drum bearing therecorded message from the machine I04. The coil 2I4 of the relay 2E6 isenergized to stop the scanner of the machine I04, and communication withthe machine I0 is maintained by maintain: ing a positive potential online LI. Its scanner is returned by opening the line L2.

The recording process may be repeated by again moving the switch to thesecond position if the central station attendant so desires. A fresh:oopyholder drum I35 will "be in position in the 15 machine I64, and thetongue I55 of the relay II will. again move'to its M contact to energizethe half-nut magnet 89. 1

If the central station attendant is satisfied with the quality of thereceived message, he moves the rotary witch to its fourth position,which applies negative potential to the line L2 to move the contacttongue I53 of the relay I51 to its S contact, which energizes the peelmagnet 51. The rotary switch is turned to the eighth position.- Inpassing over the seventh positiomthe lines LI and L2 are opened, whichshuts down-themachine I8, and in the eighth position negative potentialis applied. to the line LI, which lights the lamp 22d of the messageacceptedsign. Th'e'circuit for this may be traced from bus bar A,contact S of relay I29, a break contact 259 of relay I76, closedcontacts 25I or the multicontact switch use and the lamp 22rd. The plugI63 may be removed from the jack I64 and the rotary switch turned to itsneutral position in preparation for the next operation at the centraloffice.

If, after repeating the recording process, the central station attendantis satisfied that a good recording cannot be obtained, or if the messagei illegible, he may move the rotary switch to the sixth position, whichwill apply negative potential to the line LI to move the contact arm I52of the relay I49 to the contact S, thereby illuminating the signal lamp22e ofthe rewrite message sign by way of the contacts253 of themulticontact switch I19, which is maintained closed by keeping the lineL2 positive. The ro-' tary switch is then returned to the depositmessage position in readines to again receive the message or subjectmatter, which must be reinscribed by the patron upon a fresh messagesheet.

Fig. 5 of the drawings illustrates a modification of thetransmitter-recorder of this invention provided with means forelectively distributing message sheets removed from the copyholdingcylinder. In the illustrative embodiment of Fig. 5, twoelectromagnetically operated message sheet removing devices are shownfor selectively distributing message sheets into one or the other of twocompartments. It'will be understood'by one skilled in the art that anumber of angularly spaced message sheet removing devices may beprovided, together with a compartment or receptacle associated with eachdevice, and that any desired means for selectively operating thesemessage sheets may be employed.

The machine of Fig. 5 is substantially the same as the machine In ofFig. 1,,and therefore like parts are designated by the same referencecharacters to facilitate identification of these parts. The copyholdingcylinder I4 is positioned as before to-be fed with blanks 32 or messagesheets manually introduced into the chute 2E bywayof the slot 24. Theswitch arm 54 i operated by an arm 252 similar to the arm 52 of Fig. 1'which cooperates with a groove 5| in a'jcopyholdi'ng cylinder I4. Thecontacts 56 and 51 are shown as being interchanged in position, sincethe arm 252 lies above the cylinder I4. The stripping finger I6 iseflfective upon energization of the magnet 9! to remove a messagesheet'from the copyholding cylinder so that it is deposited in the binprcompartment I2. Access'to message sheets in the-compartment I2 isobtainedthrough'the closure I8 which, if desired, may be provided withany suitable type of lock.

'An' additional stripping finger 254 is" provided, which is adjustablysecured to a rock shaft 255 by a set screw 251. This rock shaft isjournaled 116 in any suitable manner from thesides ofthe machine It andcarries the armature 258 of a stripper magnet 259. A return. spring 26I,maintains the stripper finger out of engagement with the cylinder I4until the magnet is energized. The magnet 259-may, as shown,bemounted'at one side of the machine, and to the rear of the stripper magnet 61which operates the stripper finger i5. A.;compartmentT252 having sidewalls 263, one of which is shown, and a front wall 264 is pro; vided forreceiving message sheets ejectedfrom the copyholding cylinder 14*uponoperation of the stripping finger 254. Access to the compartmerit 262mobtained through a' closure member 256 hinged at 261 to the rear panelof the box II which houses the entire machine ID. The clo sure member26-6 maya-lso, if-desireol, be pro= vided with a lock. By selectinglocks for the closures i3 and 265 which are-opened by difierent keys, itwill be noted that message sheets of any kind removed by the stripperfinger IE-wil1 be accessible only to a person-provided with a key forthe closure I8, and likewise message sheets of any kind removed by thestripper finger 254 will be accessible only to a, person provided with akey for the closure 266.- Y

The magnets 91 and 259 may be energized in any desired manner to effectoperation of the respective stripper fingers. Fig. Gdiscloses amodification of the system of Figs. 3 and 4 for obtaining selectiveoperation of the stripper- 1ingers in a manner to cause distribution ofmessage sheets bearing recorded subject matter to the compartment I2 andmessage sheets bearing subject matter for transmission into thecompartment 262. Only the modified portions of the apparatus andcircuits of Figs. 3 and 4 are disclosed by Fig. 6. The switch arms I39aand I391) of the multicontact switch I38, when operated in acounterclockwise direction, cause operation of a selected machine It inthe manner previously described. When the contact arm I 3911 reaches itstwelfth stud, the stripper finger I6 is operated in the mannerpreviously described. The contact arm I39d in Fig. 4 also causesoperation of the stripper finger I6 when the rotary switch is operatedin a clockwise direction to the fourth stud from the neutral position.In Fig. 6'; the fourth contact'stud which cooperates with the contactarm I394; is left blank, thereb to afford an opportunity for operatingthe stripper finger 25 1. This is accomplished in'the modified system ofFig. 6 by providing a relay 269 which is responsive only to values :ofcurrent higher than those normally flowing in the line LI for operationof the polar relay I49. Themake contact2'II of this relay completes acircuithinclud-j in the peel magnet 259 from the bus barA through thecontacts 242 of ,the multicontact switch I19 to the bus bar B. Whenahigher than normal signal potential is applied to the line LI, therelay 269 will close its contacts and energize the peel magnet 259'tobring the stripper finger 254 into engagement'with the copyholdingcylinder 14. This higher potential is applied to the contact arm I351)at the fourth contact stud in a clockwise direction from the neutra'lposition. Message sheets bearing subject matter for transmission andintroduced through the chute 26 are'thus removedfrorn'the copy holdingcylinder I4 and distributed to the com partment 262.
